TAPE Transformer on the Apple M1 Ultra 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1734k | 7157.9-8631.6 t/s | ~89.5-107.9 (slow) |
| Q8 | yes | 1734k | 14315.8-17263.2 t/s | ~178.9-215.8 (slow) |
| Q4 | yes | 1735k | 25563.9-30827.1 t/s | ~319.5-385.3 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
